He may have had a HUGE fan forcing in air, I don't know..
For the 210.7 run, the hood was open, cover & filter were off, and the fan was big, but not huge...

ALL Vtec engines are sensitive to valve clearences.

Dunno bout you guys, but in australia i am pretty sure std valve checks are done every 40,000km
